Description
Elastische Abdruckmasse Um ein naturgetreues Negativ einer Zahnreihe oder irgendeines anderen Gegenstandes zu erhalten, ist es oft erforderlich, daß man auch sogenannte unter sich gehende Stellen mit ausformen muß. Aus diesem Grunde war man bestrebt, Stoffe zu finden, die elastische Eigenschaften aufweisen, aber nach der Abnahme des Abdruckes ein naturgetreues Bild ergeben. Man hat hierzu vornehmlich Alginate unter Umsetzung von Erdalkali bzw. Schwermetallsalzen in Gelform verwendet. Diese Stoffe weisen aber doch noch erhebliche Nachteile auf, indem sie nicht formlionstant sind, weil die Gelbildung an das Vorhandensein größerer Mengen von Wasser gebunden ist und durch Aufnahme oder Abgabe von Wasser die genommenen Abdrücke Volumenveränderungen unterworfen sind. Dann sind auch diese Alginatgele nicht immer mechanisch stabil, um bei nachfolgendem Gipsausguß den auftretenden Gewichtsdruck aushalten zu können.Elastic impression material. Around a lifelike negative of a row of teeth or any other object, it is often necessary that one also has to shape so-called undercuts. For this reason the effort was made to find fabrics that have elastic properties, but result in a lifelike image after the impression has been taken. You have to do this primarily Alginates are used in gel form with conversion of alkaline earths or heavy metal salts. However, these substances still have considerable disadvantages in that they are not formlionstant are because gel formation is linked to the presence of large amounts of water and through the uptake or release of water the impressions taken change in volume are subject. Then these alginate gels are not always mechanically stable either, in order to be able to withstand the weight pressure that occurs during the subsequent plaster cast.
Es wurde nunmehr gefunden, daß man elastische Abdruckmassen erhält, die insbesondere auch für die Zahnmedizin Anwendung finden und darüber hinaus auch für jeden technischen Zweck dienen können, wenn man Dispersionen elastischer Plastomere verwendet und diese mit Gips oder anderen Wasser entziehenden und dabei sich erhärtenden Stoffen innigst vermischt. Die so erhaltenen elastischen Massen haben eine völlige Formkonstanz, sind echt elastisch und lassen sich leicht für den jeweiligen Anwendungszweck herstellen. It has now been found that elastic impression materials are obtained which are used in particular for dentistry and beyond Can serve for any technical purpose if one can use dispersions of elastic plastomers used and these with plaster or other dehydrating and hardening in the process Substances intimately mixed. The elastic masses obtained in this way have a complete Shape constancy, are really elastic and can be easily adapted for the respective application produce.
Beispiele 1. 1 Teil einer Dispersion von Polyisobutylen mit einem Molgewicht von etwa 100 000 wird mit 1 Teil schnell abbindendem Gips innig durchgeknetet. Die so entstandene Masse wird zum Abdrucknehmen verwendet. Die elastische Eigenschaft tritt innerhalb 5 bis 10 Minuten ein unter nachträglicher weiterer Erhärtung und Beibehaltung bzw. Verstärkung der Elastizität. Examples 1. 1 part of a dispersion of polyisobutylene with a Molecular weight of about 100,000 is thoroughly kneaded with 1 part of fast-setting plaster of paris. The resulting mass is used for taking impressions. The elastic property occurs within 5 to 10 minutes with subsequent further hardening and Maintaining or increasing elasticity.
2. 3 Teile einer Dispersion aus Polyisobutylen mit einem Molgewicht von etwa 100 000 werden mit 1 Teil Dispersion eines Gemisches aus Polybutadien und Polyacrylnitril gemischt und mit 4 Teilen schnell härtendem Gips zu einer Abdruckmasse innigst verknetet. Auch hierbei wird nach 5 bis 10 Minuten eine elastische feste Masse gebildet, die konturengenaue und volumenbeständige Abdrücke gewährleistet. 2. 3 parts of a dispersion of polyisobutylene with a molecular weight of about 100,000 with 1 part dispersion of a mixture of polybutadiene and Polyacrylonitrile mixed and mixed with 4 parts of fast-hardening plaster to form an impression compound intimately kneaded. Here, too, after 5 to 10 minutes, it becomes elastic and firm Formed mass, which ensures precise contours and volume-stable impressions.
Selbstverständlich ist die Erfindung nicht nur gemäß den beiden Beispielen ausführbar. Es besteht auch die Möglichkeit, andere gelbildende Kolloide mit zu verwenden, wie z. B. Alginate, Pektine, poiyacrylsaures Natrium u. dgl. m. Vorteilhaft ist dabei. davon auszugehen, daß man die trockenen Massen in die Dispersionen einrührt und so die Dispersionen mit einem geeigneten Kolloidgehalt erhält. i'ATENTANSPRUCH. It goes without saying that the invention is not restricted to the two examples executable. There is also the option of adding other gel-forming colloids use, such as B. alginates, pectins, polyacrylic acid sodium and the like is in. assume that the dry masses are stirred into the dispersions and so obtain the dispersions with a suitable colloid content. i'ATENT CLAIM.

Gips), gegebenenfalls unter Zusatz von gelbildenden Kolloiden. Elastic impression material for dental and technical purposes, consisting of plastic dispersions mixed with water-removing and thereby hardening substances (e.g. plaster of paris), possibly with the addition of gel-forming substances Colloids.
